Netgear R8000 is a tri-band home router. It has three BCM43602 chipsets
two of them for 5 GHz band. Both seem the same and their firmwares
report the same set of channels. The problem is due to hardware / board
design there are extra limitations that should be respected.
First PHY should be used for U-NII-2 and U-NII-3. Third PHY should be
used for U-NII-1. Using them in a different way may result in wireless
not working or in noticeably reduced performance. Basic version of this
info was provided by Broadcom employee, then it has been verified by me
using original vendor firmware (which has limitations hardcoded in UI).
This patch uses recently introduced ieee80211-freq-limit property to
describe these limitations at DT level.
Referencing PCIe devices in DT required specifying all related bridges.
Below you can see (a bit complex) PCI tree from R8000 that explains all
entries that I needed to put in DT.

There are 3 separated controllers, one per USB /standard/. With PHY
drivers in place they can be simply supported with generic drivers.

Driver for Northstar USB 3.0 PHY has been recently added under the name
phy-bcm-ns-usb3. Add binding for it into the DT files.
The only slightly tricky part is BCM47094 which uses different PHY
version and requires different compatible value.

Driver for Northstar USB 2.0 PHY was added in 4.7-rc1 by:
commit d3feb40673 ("phy: bcm-ns-usb2: new driver for USB 2.0 PHY on
Northstar").
It should be used to let EHCI platform driver init PHY.

Add interrupt mapping for the Switch Register Access Block. Only 12

Add the Switch Register Access Block which is a special piece of
hardware allowing us to perform indirect read/writes towards the
integrated BCM5301X Ethernet switch.
We also add the 4 Gigabit MAC Device Tree nodes within the brcm,bus-axi
bus node to get proper binding between the BCMA instantiated core and
the Device Tree nodes. We will need that to be able to reference
Ethernet Device Tree nodes in a future patch adding the switch ports
layout.

There are few devices that have USB power controlled using GPIO. Linux
USB host driver (bcma-hcd) already supports this by reading vcc-gpio
from DT. Set it properly for all known devices.

In the default Broadcom SDK the shared override is activated for this
cache controller, do the same in the upstream code. Data and
instruction prefetching is not activated by default for this cache
controller on the bcm53xx SoC, do it manually like it is done in the
vendor SDK.
